Modern communication relies more and more on full digital processing technology, and full digital modulation demodulation in communication system means transmitter The digital signal processing (DSP) algorithm is adopted for the receiver and the entire communication system can be DSP chip or super Large scale integrated circuits (VL S I) devices are implemented. The computer simulation method is used for the whole digital BPSK modulation demodulation system The research can clearly understand the digital signal processing technology used in the communication system, including information source, transmission and reception The filter, interpolator and adjudicator are all implemented by digital signal processing algorithm. BPSK modulation is presented in this paper The algorithm and structure of each module of demodulation system are simulated with MA TLAB software and the time domain of each part is obtained And the frequency domain waveform diagram, the design method of system simulation is implemented to the hardware of QPSK, 16QAM and other full digital modulation demodulation system It has practical guiding significance.
